With the help of 3D modelling and machine learning, scientists think they’ve solved the mystery of the tiny earthquakes that regularly rumbled under Cahuilla, California from early 2016 to late 2019 – a period of almost four years. Some sort of natural fluid, such as water or liquid carbon dioxide, is likely to be the

The famous cat-in-a-box thought experiment by Austrian physicist Erwin Schrödinger is an illustration of one of the defining characteristics of quantum mechanics – the unpredictable behaviour of particles at the quantum level. It makes working with quantum systems incredibly difficult; but what if we could make quantum predictions? A team of physicists believes it’s possible.
Nothing rages against the dying of the light harder than a star. Their death throes are wild and violent as the star is wracked with colossal quakes, throwing vast amounts of stellar material out into the surrounding space. Studying the gas and dust thrown off in such events can help us understand how these stars
If we’re really serious about solving the climate crisis, we need to start tackling our economy’s overwhelming ‘power’ of consumption, researchers warn in a new report. While having money is often portrayed as something to aspire to, the wealthiest nations and individuals are also wreaking the most environmental destruction. If we keep heading in this
For the first time, US doctors can prescribe a video game. The Food and Drug Administration (FDA) has just approved EndeavorRX as an effective treatment for kids with attention deficit hyperactivity disorder, or ADHD. Children aged 8-12 years old can now be prescribed gaming sessions on EndeavorRX, in which players pilot a small aircraft through
WASHINGTON — Boeing announced late June 19 several changes in management of its work on the International Space Station and CST-100 Starliner commercial crew vehicle. In a memo to employees of Boeing Space and Launch, Jim Chilton, senior vice president in charge of the division, announced that Mark Mulqueen will retire from the company July
Perhaps the most iconic dinosaur is Tyrannosaurus rex, a massive predator that lived in what is now North America. We have now discovered that carnivorous dinosaurs of a similar size existed in ancient Australia as well. Following the footprints We learned about these carnivores by studying fossils that were discovered up to 90 years ago.
Deep beneath the mountains of Gran Sasso in Italy, the world’s most sensitive dark matter experiment has made a surprise detection. No, it’s not dark matter. Instead, the experiment has detected significantly more particle interaction events than predicted by the standard model of particle physics. Instead of the 232 ± 15 low-energy events expected in
It’s a mystery that’s eluded scientists for over 100 years – why do two identically coloured shapes look different when they’re placed on a gradient background? Just take a look at the image above: the two circles are the same colour. Our perception of shades (and colours) changes according to their visual context, a process
Only 566 people have ever travelled to space. Sixty-five of them, or about 11.5 percent, were women. NASA recently proclaimed it will put the “first woman and next man” on the Moon by 2024. Despite nearly 60 years of human spaceflight, women are still in the territory of “firsts”. Valentina Tereshkova, the first woman in
New survey results from 40 countries shows that climate change matters to most people. In the vast majority of countries, fewer than 3 percent said climate change was not serious at all. We carried out this research as part of the University of Oxford’s Reuters Institute annual Digital News Reports. More than 80,000 people were
Artificial intelligence networks have learnt a new trick: being able to create photo-realistic faces from just a few pixelated dots, adding in features such as eyelashes and wrinkles that can’t even be found in the original. Before you freak out, it’s good to note this is not some kind of creepy reverse pixelation that can
WASHINGTON — NASA officials say they’re confident that the Mars 2020 Perseverance rover mission will launch this summer amid the special measures the agency had to take to keep the mission on track during the coronavirus pandemic. The mission is currently scheduled for launch July 20 on a United Launch Alliance Atlas 5 from Cape
The most severe extinction in Earth’s history looks to have been preceded and enabled by a colossal coal fire lit by volcanism over 250 million years ago, according to new research. The Permian-Triassic extinction, also known as the ‘Great Dying’, constitutes the deadliest of all our planet’s mass extinction events. When it took place, approximately
In July of 2018, NASA announced an incredible achievement. They had created the coldest spot in space – right there on the International Space Station, in orbit around Earth. They took atoms of a soft metal called rubidium, and cooled them to temperatures around 100 nanoKelvin – one ten-millionth of a Kelvin above absolute zero.
Trees marked by Aboriginal cultural practices are a distinctive part of the Australian landscape. A recent discovery on Wiradjuri country in New South Wales shows some of these “culturally modified trees” may be much younger than anybody thought. What are culturally modified trees? Aboriginal people have long used bark, wood, and trees for practical and
There’s simply no denying the fact that humans have drastically altered, developed, and ransacked much of the natural world for our own ends. But how much of the planet’s surface remains free of our often malign influence? If we were to map Earth looking only for signs of humanity’s footprint on landscapes, how much of
This summer, the clean energy company SINN Power is showcasing “the world’s first floating ocean hybrid platform” – a high-tech buoy that produces electricity from not one, not two, but three sources of renewable energy. Using waves, wind, and the sun, the SINN Power floating structure, which can supposedly withstand waves up to six metres
SAN FRANCISCO – Raytheon won a National Oceanic and Atmospheric Administration contract to study High-Resolution Infrared Sounder (HIRIS), a weather instrument designed to offer detailed views of cloud tops and the dry line, where moist and dry air meet. Under the May 12 NOAA contract valued at nearly $295,000, Raytheon will spend seven months fleshing
For humans, getting whacked in the face by heavy raindrops is a mere annoyance. But for tiny and delicate organisms – like butterflies – drops of rainwater are the equivalent of a person being pummelled by bowling balls falling from the sky. Ouch. “[Getting hit with] raindrops is the most dangerous event for this kind
A liquid phase originally proposed in the 1910s has finally been realised. Using a liquid crystal compound, scientists have discovered a new “ferroelectric nematic” phase that could open up an entire new class of materials and technological advances. There are many phases of liquid crystal, but one of the most common is the nematic phase.
Israeli scientists say they have produced hydrogen from plants in a development that they hope could eventually lead to using vegetation to produce electricity. The discovery was made by using microscopic algae, an aquatic plant, in research carried out at a Tel Aviv University laboratory. “To link a device to electricity, you just have to
So much of our everyday tech runs on batteries, the importance of lithium-ion rechargeables cannot be overstated. But they are expensive to produce, with difficult-to-source materials. There is an alternative - sodium-ion batteries have the potential to be cheaper and more easily produced, if we can get past the problem of getting these batteries to work
WASHINGTON — Spaceflight Industries has completed the sale of its satellite rideshare business, Spaceflight Inc., to a pair of Japanese companies following a U.S. regulatory review and the modification of an Intelsat loan. Spaceflight Industries said the sale to Mitsui & Co., in partnership with Yamasa Co., closed June 12, roughly four months after it
Don’t you just hate it when you discover bits of yourself that seem to have a mind of their own? Like when you decide you really don’t want to like someone, but some other part of you does anyway. Well, bad news for all you fellow egg-bearers out there – turns out our ova make
It’s easy to take time’s arrow for granted – but the gears of physics actually work just as smoothly in reverse. Maybe that time machine is possible after all? An experiment from 2019 shows just how much wiggle room we can expect when it comes to distinguishing the past from the future, at least on
SASC aide: “The acquisition piece was never formally transmitted to the Congress.” WASHINGTON — The Senate Armed Services Committee approved its version of the Fiscal Year 2021 National Defense Authorization Act by a vote of 25-2 following three days of closed hearings, the committee announced June 11. The markup authorizes $740.5 billion for national defense
Gen. Raymond: “These men and women “made the bold decision to volunteer to join the U.S. Space Force and defend the ultimate high ground.” WASHINGTON — More than 8,500 active-duty airmen applied to join the U.S. Space Force during the month of May, the service announced on June 9. Applicants include a mix of officers
WASHINGTON — NASA announced June 5 that it awarded a contract to Northrop Grumman to begin work on a habitation module for the lunar Gateway, nearly a year after the agency announced its intent to sole-source that module to the company. NASA said it issued a contract to Northrop Grumman valued at $187 million for
WASHINGTON — The reelection campaign of President Donald Trump has taken down an online ad tied to the recent Demo-2 commercial crew launch after complaints it appeared to violate NASA media guidelines, and criticism from one person who appeared in it.
